The device includes: a cooling external tube in which a pair of cooling water pipes respectively are connected to one side and the other side that is opposite to the one side, of the cooling external tube and a cooling internal tube installed in the cooling external tube; a plurality of refrigerant circulating pipes, which are continuously installed inside and outside the cooling internal tube in a spring shape, extend thereto and have ends connected as a refrigerant circulating path of a cooling cycle through a bottom portion of the cooling internal tube and a bottom portion of the cooling external tube; and a plurality of drinking water pipes, which are adjacent to the refrigerant circulating pipes and are continuously installed inside and outside the cooling internal tube and in which drinking water is flowed in an end of the cooling internal tube, is rapidly cooled and is discharged into an end of the cooling external tube.

TECHNICAL FIELD

The present invention relates to a multilateral continuous uniform rapidcooling device in which drinking water can be rapidly and uniformlycooled through cooling circulation using a drinking water pipe that isconstituted separately from a refrigerant circulating pipe and a coolingwater pipe, and more particularly, to a multilateral continuous uniformrapid cooling device of a double cooling structure in which drinkingwater such as a beverage or liquor can be rapidly and continuouslydischarged without limitation of amount immediately at an optimumcooling temperature to drink and can be drunken.

BACKGROUND ART

Generally, a water cooler and heater is constituted to allow directwater (original water) that is basically clean or purified water that ispurified using an additional filter to be flowed in a cold water tank(water tank) and a hot water tank (water tank) and to discharge water ina cold or hot water state into an exhaust tap by performing an exhaustoperation of the exhaust tap.

In particular, the need for a cooling device that allows purified waterstored in a cold water tank to be maintained in a cooling state within ashortest time is very important. In an indirect cooling method of therelated art, a refrigerant pipe is wound around the outside of the coldwater tank to a predetermined length and functions as an evaporator sothat water stored in the cold water tank can be cooled.

However, in the indirect cooling method, as water flowed into the coldwater tank as much as water flowed out toward the outside of the coldwater tank increases, some water is stored in the cold water tankaccording to the capacity of a water tank. However, inflow water andoutflow water are mixed with each other, and the temperature of waterrises rapidly. Also, due to the indirect cooling method, a difference inthe temperature of water exists between inside and outside of the coldwater tank and upper and lower portions of the cold water tank.

In addition, in order to solve a problem of the indirect cooling method,in the related direct cooling method, water that is stored in the coldwater tank and purified by installing a cooling rod (heat absorptioncylinder) having the refrigerant pipe in the cold water tank can bedirectly heat-exchanged by using the cooling rod. Unlike the indirectcooling method, cooling heat that is transferred from the refrigerantpipe can be used, and thus, cooling efficiency is higher than in theindirect cooling method.

However, in both the related direct and indirect cooling methods, when alarge amount of cooled water stored in the cold water tank is flowed outwithin a short time, there is a limitation of a cooling structure inwhich uncooled and tepid water is flowed out. This is because there is alimitation of a direct cooling function due to a cooling plate that isdisposed in a horizontal direction and protrudes from a plurality ofspiral layers based on a cooling rod (heat absorption cylinder) that isinstalled in a vertical direction and in the middle of the most space ofthe cold water tank in which water is stored.

In other words, in the related art, water is cooled by inserting orwinding the refrigerant pipe in or around the inside or outside of thecold water tank. In the related cooling device, cooling effect occursonly in a portion where water contacts the refrigerant pipe. Thus, theamount of cold water is small, and time required for cooling water againincreases. Thus, excessive energy is wasted, and as such, energyefficiency is lowered.

Meanwhile, in Korean Patent Laid-open Publication No. 10-0770093(entitled Multilateral Continuous Uniform Rapid Cooling Device) whichhas been already filed by the present applicant and of whichregistration has been decided, that is, in a cooling device in which,when a refrigerant pipe through which a refrigerant passes and iscirculated is installed in a cooling rod 40 of a cold water, a pluralityof separation plates 30 that disperse the flow of water are installedoutside the cooling rod 40 at regular intervals, as shown in FIG. 1, ahorizontal refrigerant pipe 20 a and an eddy current directionrefrigerant pipe 20 b in which a flow path of the refrigerant iscontinuously formed are installed as a single body in the cooling rod40, and a bottom end of the eddy current direction refrigerant pipe 20 bof the cooling rod 40 is connected to refrigerant pipes 22 a and 22 b,which are installed along the separation plates 30 installed outside thecooling rod 40.

Also, the refrigerant pipes 22 a and 22 b are installed along theseparation plates 30 to have the same radius from downwards to upwards,do not overlap with each other from upwards to downwards, and passthrough a lower portion of a cold water tank 10. Also, owing toconstruction in which an inlet 12 a and an outlet 12 b are perforated sothat water is flowed in top and bottom ends of the cooling rod 40 andpasses through the cold water tank 10, purified water that is flowed inthe cold water tank 10 directly and continuously contacts therefrigerant of the refrigerant pipes 22 a and 22 b in a multilateralshape and can be rapidly cooled within a short time.

However, in the above-mentioned technology by the present applicant, therefrigerant pipe in which a cold refrigerant is circulated is installeduniformly inside the cooling rod and the cold water tank so thatpurified water that is flowed in the cold water directly andcontinuously contacts the refrigerant of the refrigerant pipe in amultilateral shape and can be rapidly cooled within a short time.However, drinking water such as a beverage or liquor needs to be cooledimmediately and to be drunken, and the related cooling device does notprovide a cooling structure in which drinking water passes and iscooled.

Referring to FIGS. 2, 3, and 4, the multilateral continuous uniformrapid cooling device of a double cooling structure according to thecurrent embodiment includes a cooling external tube 10 in which coolingwater pipes 60 a and 60 b are connected to one side and the other sidethat is opposite to the one side, of the cooling external tube 10, acooling internal tube 40 installed in the cooling external tube 10, aplurality of refrigerant circulating pipes 20 a and 20 b, which arecontinuously installed inside and outside the cooling internal tube 40in a spring shape, extend thereto and have ends connected as arefrigerant circulating path of a cooling cycle through a bottom portionof the cooling internal tube 40 and a bottom portion of the coolingexternal tube 10, and a plurality of drinking water pipes 50 a and 50 b,which are adjacent to the refrigerant circulating pipes 20 a and 20 band are continuously installed inside and outside the cooling internaltube 40 and in which drinking water is flowed in an end of the coolinginternal tube 40, is rapidly cooled and is discharged into an end of thecooling external tube 10. Drinking water such as a beverage or liquor isflowed in the drinking water pipe 50 a, is heat-exchanged in a doublemanner by using the refrigerant circulating pipes 20 a and 20 b that areequally installed in the space of the cooling internal tube 40 and thecooling external tube 10 in a spiral shape and by using cooling waterthat is cooled by heat exchange of the refrigerant circulating pipes 20a and 20 b in which the refrigerant is circulated and supplied so thatdrinking water can be uniformly and rapidly cooled in a multilateralshape by using the double cooling structure of the present invention.

In other words, unlike the related cooling device, in the presentinvention, a plurality of refrigerant pipes of a general cooling cycleare equally installed in the cooling external tube 10 and the coolinginternal tube 40 that constitute a cooling water tank, in a spring shapeso that one end and the other end of each of the refrigerant pipes areagain connected to the cooling cycle. Basically, additional drinkingwater pipes 50 a and 50 b in which drinking water is supplied andcirculated are installed at the cooling external tube 10 and the coolinginternal tube 40 together with the refrigerant circulating pipes 20 aand 20 b. Direct water or purified water is supplied and circulated inthe cooling external tube 10 and the cooling internal tube 40, iscooled, and is stored as cooling water of a predetermined temperature.

Firstly, the cooling internal tube 40 may be installed in a verticaldirection in the middle of the cooling external tube 10, and a pluralityof bypass holes may be formed in the bottom portion of the coolinginternal tube 40 together with the cooling external tube 10 so that thecooling water pipes 60 a and 60 b as well as the refrigerant circulatingpipes 20 a and 20 b and the drinking water pipes 50 a and 50 b,respectively, communicate with the cooling internal tube 40. Inparticular, the cooling water pipe 60 b may be installed at an outlet ofthe cooling external tube 10, and the cooling water pipe 60 a may beinstalled at an inlet of the cooling external tube 10 so that coolingwater stored in the cooling external tube 10 can be circulated andsupplied to an auxiliary tank 70. One end of each of the cooling waterpipes 60 a and 60 b is connected to the cooling external tube 10, andthe other end thereof is connected to the auxiliary tank 70.

One end of each of the refrigerant circulating pipes 20 a and 20 bincluding a compressor 24, in which the refrigerant is circulated in ageneral cooling cycle is connected to the cooling internal tube 40 andextends thereto, and the other end of each of the refrigerantcirculating pipes 20 a and 20 b that extend through the cooling externaltube 10 is again connected to the refrigeration pipe in the coolingcycle. Referring to FIGS. 2, 3, and 4, the refrigerant circulating pipes20 a and 20 b are primarily installed in the cooling internal tube 40 ina spring shape, are secondarily installed in the cooling external tube10 and are positioned in the cooling space of the cooling internal tube40 and the cooling external tube 10 in a spiral shape.

In addition, in order to supply and cool drinking water such as liquoror various kinds of beverages immediately when the refrigerantcirculating pipes 20 a and 20 b in which the refrigerant is circulatedin the cooling cycle are separately used, a beverage pipe 20 a which isone of the refrigerant circulating pipes 20 a and 20 b is primarilyinstalled in a vertical direction in the cooling internal tube 40 in aspring shape to have the same structure as the refrigerant circulatingpipes 20 a and 20 b, and subsequently, the beverage pipe 20 a installedin the cooling internal tube 40 is also continuously installed in thecooling external tube 10, and the beverage pipe 20 b which is the otherone of the refrigerant circulating pipes 20 a and 20 b, extends to theexternal through the cooling space of the cooling internal tube 40, andthe cooling external tube 10 and an exhaust tap 34 is installed at anend of the beverage pipe 20 b so that drinking water of room temperaturethat is supplied immediately can be uniformly heat-exchanged in amultilateral shape in a double manner by using the refrigerantcirculating pipes 20 a and 20 b and cooling water that is filled in thecooling internal tube 40 and the cooling external tube 10 and can bedischarged in a rapidly-cooled state.

In addition, both ends of the cooling water pipes 60 a and 60 b areconnected to the cooling external tube 10 and the cooling internal tube40 in which the refrigerant circulating pipes 20 a and 20 b and thedrinking water pipes 50 a and 50 b form the entire cooling space in aspring shape. The cooling water pipe 60 b which is connected to one sideof the cooling external tube 10 and extends thereto, is connected to oneside of the auxiliary tank 70 installed on the cooling external tube 10,and an end of the cooling water pipe 60 a which is connected from theother side of the auxiliary tank 70 and extends thereto, is connected tothe other side of the cooling internal tube 40.

As such, cooling water from the cooling internal tube 40 and the coolingexternal tube 10, respectively, can be discharged into the auxiliarytank 70 through the cooling water pipes 60 b and 60 a and subsequentlycan be flowed in the cooling internal tube 40 and the cooling externaltube 10 and can be circulated. In particular, a circulating pump 62 isinstalled in the middle of the cooling water pipe 60 b connected to oneside of the cooling external tube 10 so that cooling water from thecooling external tube 10 can be smoothly flowed in the auxiliary tank 70and subsequently can be supplied and circulated to the cooling internaltube 40.

In particular, a faucet 52 may be installed at the cooling water pipe 60a which is one of the cooling water pipes 60 a and 60 b connecting thecooling external tube 40 and the cooling internal tube 10 to theauxiliary tank 70 so that cold drinking water and cooling water can bedischarged and drunken during using.

Meanwhile, an air inlet 72 may protrude from the bottom portion of theauxiliary tank 70 installed above the cooling external tube 40 and maycommunicate with the upper portion of the cooling external tube 10 sothat cooling water filled in the cooling external tube 10 can besmoothly circulated and supplied through the cooling water pipes 60 aand 60 b, and a water supply hole 74 may be formed in the upper portionof the auxiliary tank 70 and may be open or closed by using a sealingstopper 76 so as to supplement or discharge water (cooling water). Anair entering hole 14 may be perforated in the upper portion of thecooling external tube 40 in the same position as the air inlet 72 of theauxiliary tank 70.

In addition, a temperature sensor 80 is installed to sense a change oftemperature of cooling water and control the temperature so that coolingwater stored and circulated in the cooling internal tube 40 and thecooling external tube 10 can be maintained at an appropriate coolingtemperature. If cooling water exceeds a predetermined, appropriatetemperature, constructions of the general cooling cycle operateautomatically, and refrigerant supply and circulation of the refrigerantcirculating pipes 20 a and 20 b installed at the cooling internal tube40 and the cooling external tube 10 can be automatically controlled andsmooth heat exchange can be performed.

Furthermore, an additional circulating pump may be installed so thatdrinking water can be smoothly supplied and circulated over the coolingexternal tube 40 and the cooling internal tube 10 through the drinkingwater pipes 50 a and 50 b. Unexplained reference numeral 54 denotes afaucet through which drinking water can be supplied to the drinkingwater pipe 50 a which is one of the drinking water pipes 50 a and 50 b,and the construction relationship and operating principle of the presentinvention is not limited thereto.

In addition, a plurality of spiral separation plates (dispersiondiaphragms) may be formed outside the cooling internal tube 40 and mayprotrude between the refrigerant circulating pipes 20 a and 20 b and thedrinking water pipes 50 a and 50 b so that mass of cooling water that isa fluid can be dispersed and multilateral continuous contact between therefrigerant circulating pipes 20 a and 20 b and the drinking water pipes50 a and 50 b can be increased. Also, according to another embodiment,by using FIG. 1 as the related art that has been filed by the presentapplicant as a basic embodiment, the separation plates may be installedin a horizontal direction in a spiral shape by using the coolinginternal tube 40 as a medium, and a plurality of wing diaphragms may beinstalled on the separation plates at regular intervals so that thespeed of water that is dropped along the cooling internal tube 40 can bedispersed and delayed and time required for heat exchange contactbetween the drinking water pipes 50 a and 50 b through which drinkingwater passes can be extended.

When the refrigerant circulating pipes of the cooling cycle are used asa heating means, the multilateral continuous uniform rapid coolingdevice of the double cooling structure according to the presentinvention in which drinking water can be rapidly and uniformly cooledthrough cooling circulation using a drinking water pipe that isconstituted separately from a refrigerant circulating pipe and a coolingwater pipe, can be used as a multilateral continuous uniform rapidheating device of a double heating structure for immediately heatingcontents.

FIG. 5 illustrates a structure of a multilateral continuous uniformrapid cooling device of a double cooling structure according to anotheraspect of the present invention.

Hereinafter, a detailed description of the same structure as that ofFIG. 2 will be omitted, and a different portion from that of FIG. 2 willbe described.

Referring to FIG. 5, the multilateral continuous uniform rapid coolingdevice of a double cooling structure according to the current embodimentincludes a cooling internal tube 140, a cooling external tube 110, aplurality of refrigerant circulating pipes 120 a and 120 b, a pluralityof drinking water pipes 150 a and 150 b, and a plurality of coolingwater pipes 160 a and 160 b.

One end of one (the cooling water pipe 160 a) of the cooling water pipes160 a and 160 b is connected to the cooling internal tube 140, and oneend of the other one (the cooling water pipe 160 b) of the cooling waterpipes 160 a and 160 b is connected to the cooling external tube 110through a lateral connection portion 110 a that is separated from thebottom side of the cooling external tube 110.

One end of the refrigerant circulating pipe 120 a is connected to abottom side of the cooling internal tube 140, and one end of therefrigerant circulating pipe 120 b is connected to a side that isseparated from a bottom side of the cooling external tube 110.

In the multilateral continuous uniform rapid cooling device of a doublecooling structure according to the current embodiment, the refrigerantcirculating pipe 120 b is connected through a lateral connection portion110 a that is separated from the bottom side of the cooling externaltube 110. As such, the flow amount of cooling water of portion A that ispositioned at a lower side of the lateral connection portion 110 a ofcooling water inside the cooling external tube 140 is remarkably reducedcompared to that of cooling water that is positioned at an upper side ofthe lateral connection portion 110 a, and cooling water around therefrigerant circulating pipe 120 b is gradually changed into ice. Aregion in which cooling water is changed into ice gradually extends tothe drinking water pipes 150 a and 150 b.

Cooling water that is positioned in an upper position than the lateralconnection portion 110 a of the cooling external tube 110 iscontinuously circulated and thus is not changed into ice. That is, whenthe temperature of cooling water is 3 degrees below zero that is lessthan a freezing point, cooling water briskly flows in an uncooled stateat the upper side of the lateral connection portion 110 a of the coolingexternal tube 110 and is heat-exchanged with the drinking water pipes150 a and 150 b. However, cooling water that is positioned at the lowerside of the lateral connection portion 110 a of the cooling externaltube 10 is not smoothly circulated, and when the temperature of coolingwater is 3 degrees below zero that is less than a freezing point,cooling water is changed into ice.

In this case, drinking water that flows through the drinking water pipes150 a and 150 b is heat-exchanged with cooling water at the upper sideof the lateral connection portion 110 a and is cooled. Simultaneously,the temperature of cooling water that is heat-exchanged with drinkingwater rises relatively.

Cooling water of the rising temperature moves toward the lower side ofthe lateral connection portion 110 a, is heat-exchanged with ice that isformed around the refrigerant circulating pipe 120 a and is cooledagain. Meanwhile, drinking water that is cooled by using cooling waterfilled at the upper side of the lateral connection portion 110 a movesdownwards along the drinking water pipes 150 a and 150 b, isheat-exchanged with cooling water that is cooled by using ice and iscooled again. In this case, cooling water is cooled by using latent heatof cooling water that is changed into ice, and drinking water is cooledby using cooled cooling water so that drinking water can be moreefficiently cooled.

Cooling water that is changed into ice and is positioned around therefrigerant circulating pipes 120 a and 120 b is gradually changed intowater, and the temperature of cooling water rises gradually. Coolingwater of the rising temperature moves toward the inside of the coolinginternal tube 140 through a plurality of bypass holes 140 a formed inthe bottom portion of the cooling internal tube 140 and then is mixedwith cooling water that is flowed through the refrigerant circulatingpipes 120 a and 120 b, is cooled and then moves upwards and iscontinuously circulated in a cooled state in the cooling internal tube140 and the cooling external tube 110.

Cooling water that flows through a cooling water pipe through thelateral connection portion 110 a of the cooling external tube 110 movesalong the cooling water pipe by using a pump and then is directlysupplied to the upper side of cooling water that is accommodated in thecooling external tube 110.

As cooling water that is supplied through the cooling water pipe dropsand is fallen into the upper side of cooling water of the coolingexternal tube 110, severe flow occurs in the upper portion of coolingwater of the cooling external tube 110. Thus, heat-exchange efficiencyinside the cooling external tube 110 is further improved.

FIG. 6 illustrates a structure of a multilateral continuous uniformrapid cooling device of a double cooling structure according to anotheraspect of the present invention. The multilateral continuous uniformrapid cooling device of a double cooling structure according to thecurrent embodiment includes a cooling internal tube 240, a coolingexternal tube 210, a plurality of refrigerant circulating pipes 220 aand 220 b, a plurality of drinking water pipes 250 a and 250 b, aplurality of cooling water pipes 260 a and 260 b, a heat exchanger 300,and a ventilation fan 310.

The structure of the cooling internal and external tubes 210 and 240,the refrigerant circulating pipes 220 a and 220 b, and the drinkingwater pipes 250 a and 250 b is the same as that of FIG. 2, and thus, adescription thereof will be omitted, and a difference between FIGS. 2and 6 will be described in detail.

The multilateral continuous uniform rapid cooling device of a doublecooling structure according to the current embodiment further includes afirst branch pipe 261 that is diverged from the middle of the coolingwater pipe 260 b, and the first branch pipe 261 is connected to an inletport of the heat exchanger 300. The cooling water pipe 260 a includes asecond branch pipe 262 that is diverged from the middle of the coolingwater pipe 260 a, and the second branch pipe 262 is connected to anoutlet port of the heat exchanger 300.

A ventilation fan 310 is positioned at a side of the heat exchanger 300.Owing to the ventilation fan 310, forcible flow of the air that passesthrough the heat exchanger 300 is well performed, and heat exchangeefficiency of cooling water that flows in the heat exchanger 300 isimproved, and simultaneously, the cooled air is supplied to apredetermined position in which cold wind is required so that cold windeffect can be shown.

The operation of the multilateral continuous uniform rapid coolingdevice of a double cooling structure according to the current embodimentwill be described in greater detail. Approximately half cooling waterthat flows through the cooling water pipe 260 b is flowed in the heatexchanger 300 through the first branch pipe 261, and cooling water thatis flowed in the heat exchanger 300 is heat-exchanged with the air andis used to cool the air and then flows in the cooling water pipe 260 athrough the second branch pipe 262. Cooling water that flows in thecooling water pipe 260 a is flowed in the cooling external tube 210, isagain cooled in the cooling external tube 210 and the cooling internaltube 240 and moves toward the cooling water pipe 260 b and iscontinuously circulated.

The air that passes through the heat exchanger 300 is sufficientlycooled by cooling water that passes through the heat exchanger 300, andthe cooled air is supplied by the ventilation fan 310 to the outside sothat cold wind effect can be shown.

Accordingly, the multilateral continuous uniform rapid cooling device ofa double cooling structure according to the present invention has anadvantage of having a function of a wind cooler that cools the air andsupplies the air to a predetermined position in which cold wind isrequired, by installing further heat exchanger without an additionalcooling system.
